Seventeen-year-old Lacey Burke is the last person on the planet who should be doling out sex advice. For starters, she’s never even kissed anyone, and she hates breaking the rules. Up until now, she's been a straight-A music geek that no one even notices. All she cares about is jamming out with her best friends, Theo and Evita.

But then everything changes.

When Lacey sees first-hand how much damage the abstinence-only sex-ed curriculum of her school can do, she decides to take a stand and starts doling out wisdom and contraception to anyone who seeks her out in the girls' restroom. But things with Theo become complicated quickly, and Lacey is soon not just keeping everyone else’s secrets, but hers as well.
